FOAMFlask is an attempt to make a yet another lightweight web-based GUI for managing and running OpenFOAM tutorials and simulations. It allows users to easily select a tutorial, set a case directory, and execute OpenFOAM commands directly from a browser. Since this is targeted for beginners, the documentation has been kept as extensive as possible. FOAMFlask works on Windows, Linux and MacOS.

Important

1. Currently only loading and execution of OpenFOAM tutorials ($FOAM_TUTORIALS) is supported. Creating custom cases is planned.

2. Always edit files in static/ts/ directory, never directly in static/js/. The static/js/ files are overwritten during the build process.

• Web interface for OpenFOAM case management.
• Persistently store the CASE_ROOT across sessions.
• Load and copy tutorials from the OpenFOAM tutorials directory.
• Run common OpenFOAM commands (blockMesh, simpleFoam, pimpleFoam) with live output.
• Color-coded console output for stdout, stderr, info, and tutorial messages.
• Fully compatible with OpenFOAM 2506 (adjustable for other versions).
• Security-hardened command execution with input validation and injection protection.
